To all whom t may concern.

Be it known that l, donn W. Goonwrn, a citizen of the llnited States,residin at Neodesha, in the county of Wilson, tate of Kansas, haveinvented a new and usetul Metal Form for Constructing Silo and otherCement Walls; and l do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to an` improved metal torni. for constructingsilo and other cement walls, and one of the objects ofthe invention isto provide a simple, eilclent and practical form of this kind comprisingtic material may be deposited therebetween inner and outer sheet metalmembers, between which sections of 'a silo or other wall may beconstructed, each section of the wall being constructed successivelyuntil the entire wall isy constructed.

A. further object ot the invention is the provision of improved meansfor holding the inner and outer sheet metal members in spaced relations,one rigid with relation to the other, whereby the cement or other plastoform the section of wall.

A further, object of the invention is the provision of means for holdingthe inner and outer sheet metal members in adjusted spaced relation,whereby walls oil did'erent thicknesses may be constructed, or wallsthicker at one end than at the other may be constructed..l

A further object oit the invention is the provision of improved meansfor bowing the inner and outer sheet metal spring members on diderentarcs, whereby walls of dif- :ferent diameters may| be constructed.

lln practical elds the details ot construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further :features and combinations ot parts ashereinafter set forth, shown in the drawings and; claimed.

1n the drawings Figure 1 is a plan view of the inner and outer sheetmetal members, bowed so as to construct a curved wall, which mayconstitute a section ol a silo wall.

Fig. 2 is a horizontal sectional view of said sheet metal formcomprising said inner and outer sheet metal plates.

Fig. 3 is a detail perspective view ot the inner and outer sheet metalspring plates or members, showing the means for holdin them in did'erentadjusted positions an spaced trom each other end plates, whereby the endot the wall lto be constructed may be formed, to constitute a art ot adoor jamb.

ig. d is a sectional view on line 4--4 ol which cement or other plasticmaterial is designedto be deposited to form a section of a silo forother wall. Each end of the outer 0plate 2 is provided with an outwardlyturne radially disposed flange 3. To the ends of the inner sheet metalplate 1 plates or members t are connected by the hinges 5. The plates dare provided with elongated slots 6. lln order to form either endsurtace (which may constitute a door jamb or the like) ofthe wall asshown in Fig. 1, one or the other ot said plates d, is arranged tooverlie the dange 3, there being bolts i passing through the flanges 3and through the slots 6, to receive the nuts 'la to assist in holdingthe inner and outer plates in dit ferent adjusted spaced relations.

Carried by the outer 8. The arms 9 ot these strips or straps eX- tendthefull height of said outer plate 2 and are riveted thereto as shown at10, while the arms 11 overlie the upper edge of the plate 2. Pivoted tothe are the links 13, which are provided with slots 1t. ldiveted at 15to the inner plate 1 are the angular brackets 16 and extending throughthe slots 14: and through the arms 17 ot said brackets 16 are the bolts18 having nuts 19. By this construction the inner and outer plates 1 and2 may be held in did'erent adjusted spaced relations according to thethickness ol wall to be constructed'. By means of the long arms 9 of theangular straps or strips (which are rigid with relation to the arms 11and at right angle thereto) the entire height of the outer plate 2.isheld in parallelism with the inner plate 1. The inner plate adjacent itsends and near the upper and lower edges angular brackets 20 are rivetedas shown at 21. The

and the hingedly j arms 1l as shown at 12' plate 2 near its ends,

' nected, by passingk their angular end 37 1n parallelism with the outerplate inner plate 1 near its upper and lower edges is provided with eyes22" through which the rod sections 23 extend. Pivoted to the brackets'20as shown at 24 are rod sections 25, which are in turn connected to theend rod sections 23' by means of turn buckle sleeves 26. The end rodsections 23 are in turn vconnected to the central rod section 23 by thethreaded' turn buckles 27, and it is `to be observed that by adjustingthe turn b'uckles 26 and 27 in one direction, the rod sections 23 may bemoved axially toward each other, whereby the inner plate 1 may be curvedon di'erent arcs. By means of the eyes 22 the rod sections are held, sothat the plate 1 may assume a curved sha e concentric with the rodsections, and w ereby a cement wall maybe constructed havin the desiredcurvature. The outer face o lthe outer plate 2 is also provided witheyes 28,- through which the rod sections 29 ass, there being turn bucklesleeves 30threa ed to and connecting the rod sections 2 9. Additionalrod sections 31 are connected to the end rod sections 29 by theturnbuckle sleeves 32. Said rod sections 31 (which are adjacent the upperand lower edges ofthe outer plate 2) are pivoted at 33 to the angularbrackets 34.

f It is to be noted that by adjusting the turn 30 buckle sleeves 30 and32 in the desired direction the rod sections 29 and 31 may be axiallyextended, thereby giving the outer plate 2 the desired curvature,l toconform concentrically with the curvature of the inner plate. The innerplate 1 at its ends near its lower edge is provided with angularbrackets 35, to which the rods 36 are conthrough the openings 38. Theadjacent ends of the rods'36 are threads, and connecting these threadedends is a turn-buckle sleeve 39. By adjusting the turn buckle sleeve 39in the desired direction thereby moving the rods 36 axially away tromeach other, the inner plate 1 may be reinforced, and its oposite endsnear its lower edge may be he d therebyl preventing displacement of the2 andplate. In constructing a silo wall substantially as shown in Figs.1 and 2, starting from one jamb of a door opening of a silo, the plates1 and 2 (which are constructed of sprlng sheet steel) are arranged withrelatlon to each other as shown and curved so as to receivercement o rother plastic material between them. In order to form an end (which mayconstitute a jamb of a door opening), the plate 4 on the left isarranged as shown in Flgs. 1 and 3, and by means of the bolts 7 theplates 1 and 2 are prevented from becoming displaced, in fact preventedlfrom spreading. After one section of the wall is constructed said plates1 and 2 may be moved to another position to form another segment ofwall. This is continued, forming the various sections successivelyannularly, and one tier of sections on the other, until a complete silomay be constructed.

v-The invention having been set forth what is claimed as new and usefulis In a metal form for molding cement segment wall sections, inner andcuter sheet metal spring plates, means carried by the outer faces ofboth plates for giving said plates concentric curvature, angularbrackets on the inner plate near its ends and adjacent its upper edge,angular straps on the outer plate near its ends, one arm of each .strapextending the full height of the plate, and adjustable connectionsbetween said angular brackets and the angular straps for adjusting theinner and outer plates in spaced relation to each other, a transverseplate hingedly connected to each end of the inner plate and providedwith adjustable connections with the corresponding end of the outerplate, whereby the end of the segment wall may be formed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN W. GOODWIN.
